Help with LED's on headphones synchronized to music.

I want to be able to put LED lights in my SkullCandy headphones and have them synchronize to the music or at least light up and look cool. Maybe I could throw in a 555IC and have the LED's blink from left to right. I have read online how to do it and I'm stuck. If someone could please explain how to do it or show me in a video. I have a multimeter and such. I don't know the model number or model name of the headphones. I will post pictures of the headphones and where I want the LED's. I don't think this matters much but I want to use high-intensity bright green LED's. I know how to take them apart. I would prefer if I didn't have to use a transistor, but if I have to then I will. Please send me a schematic or something. Thanks.

On the picture where I am pointing that is where I want the LED's.

Might want to post a link to where you saw it online, so people would know exactly what you're trying to do.

Mine are very similar to these. The only difference is the year of manufacture and I don't have padding on the top.
